first thanks for posting so fast your exporter.
But I can't get blend material to work, I tried to follow your instructions but everything's not clear.
I want to get a nice grass material as seen on radiance's render here
So here is my setup in blender :
a uv-mapped grass, named a
a uv-mapped alpha-map for the grass, named b
and the blend material, named herbe.blend.a.b
And translucency=1 ,ambient=1 on that last material.
Then I get this error message when I launch indigo : "could not find element 'path' in element 'blend_map'"
What do I make wrong ?
I tried to put translucency=1 on the "b" material, but I get the same error.
I had a look at the xml file, and both "a" and "b" materials are defined twice, once as a <phong_material>, and once as a <null_material>. As far as I understood, only the "b" material should be a <null_material> ?
And moreover, the <blend_path> is empty in the blend material (herbe.blend.a.b).
So I don't know if it is a bug or if I make something wrong.
I wanted to point this because I REALLY
need to be able to use blend materials directly from blender.
Thanks very much for any help !
